Peace of Mind

Once Buddha was travelling with some disciples, when they happened to pass a lake. They decided to stop and rest awhile. One of his most restless disciples decided to avail of this opportunity to ask his master to explain how he could manage his mind. Buddha ignored his question and said to him, "I am thirsty. Please get me some water from that lake there." 
As the disciple approached the lake, a bullock cart started crossing through it. and the water became muddy and turbid. Buddha's disciple thought, "How can I take this dirty water to my master to drink!" He returned and said, "The water in there is very muddy. I don't think it is fit to drink."
After half an hour, Buddha asked his disciple to go again, but the water was still too muddy and the disciple returned empty handed.

On the third attempt the disciple found that the mud had settled down and the water was sparkling clean. So he collected some water in a pot and brought it to the Buddha. 
The Buddha looked at the disciple and said, “Do you see what you did to make the water clean? You let it be.... and the mud settled down on its own - and you got clear water.
Your mind is also like that!
When it is disturbed, just let it be.
Give it a little time. It will settle down on its own.
You don't have to put in any effort to calm it down.
It will happen. It is effortless." 
What did Buddha emphasize here?
He said, "It is effortless."

Having 'Peace of Mind' is not a strenuous job;
it is an effortless process!

So let us keep smiling not because of something, but in spite of everything!!
